<h2>集群配置</h2>
<h2><strong>集群概念</strong></h2>
<p>一个集群有一个kong或者多个kong组成。如果是多个kong则共用一个postgres数据库，即一个集群中多个kong的数据是共享的。</p>
<h2><strong>集群搭建</strong></h2>
<p>1.同一个集群名称，且指向同一个redis。
即在配置文件/etc/kong/kong-ext.conf中，
group和redis_hosts配置相同</p>
<p>2.连接同一个postgres。
即/etc/kong/kong.conf中pg_host值相同</p>
<h2><strong>集群管理</strong></h2>
<p>kongAdmin管理端支持管理多个集群，如下图：</p>
<p><img src="11_images\11-1.1.png" alt="1111" /></p>
<p>当有多个集群管理权限登录的用户可以通过下拉框选择相应的集群去管理。
如果用户所在集群均未启动，则用户登录不了系统。</p>
<p>同时如果有必要，可以绑定同一个集群下不同的kong，这样即使某一个kong不可用时，可以有其它的选择，如下图：</p>
<p><img src="11_images\11-1.2.png" alt="1112" /></p>
